To all whom it may concern:

Be it known that I, GILBERT F. QUINN, a citizen of the Fnited States, residing at Re Vere, in the county of Suffolk and State of Massachusetts, have invented a new and useful Rubber I-Ieel,'of which the following is a specification.

The object of my inventionis to provide a rubber heel which can be securely attached 'to the shoe withoutthe use of cement, and which will yet contain the. desirable air cushion unimpaired in its function.-

It. is further my obje'ct to provide a rubber heel conforming to the standard thickness of rubber heels for mens shoes on its outer surface and having an additional raised central platform and beveled surface to take up extra wear, and to cause the heel to maintain a vsightly appearanc e for a longer period.

In the accompanying drawings, illustrat-r ing my invention, Figure 1 shows the heel attached to a shoe; Fig. 2 is a top plan of my invention; Fig. 3 is a bottom plan of the same; Fig. 4:. is a section on line 4- of Fig. 2; and Fig. 5 is a similar section of the heel attached to a shoe.

Like numerals designate like parts in the several views.

Referring to the accompanying drawings,

stantial upturned rim at extending around the heel. This rim has an inside beveled surface 5 and an outside beveled surface 6, the two surfaces being beveled to an unequal degree but surface 6 being of greater lehgth and bevel than surface 5. Beveled surfaces 5 and 6 converge outwardly, the -outside rim face 3 being .disposed at approximately right angles to the inner surface 5 so that after the heel is attached to the shoe, rim face 3 is in alinem'ent with the side face of the heel, thereby obviating the usual practice of trimming the rubber heel; and surface 6, having a greater bevel than surface 5 which latter surface rests fiat 'to that assumed against the heel, presents a slanting surface to take up additional wear and is d sposed at an angle' corresponding approximately by the foot as it strikes the ground in natural walk. The wear is taken up principally by the raised central platform 10. in the upper fhrm an air cu$h1 find llius increase the converge outwardly, I scribed.

portion of the, heel-3L1; provide a chem fered portion '7 to resilience and decrease the amount of rubber used. Extending around chamfered portion 7 I provide a nail hole rim 8 having a flat face surface parallel with thesurface of the heel of the shoe. I further provide a sultable number of nail holes 9 extending 3 through the rim.

In use the nail hole rim 8 arrests the descent of the heel at the proper degree as its face is perfectly parallel'with the surface of the heelof the shoe, and it thus tact such as would cause the heel washer embedded in the heel to 'work up and down on the nails. and eventually wear the nailhead through the washer.

The converged outside rim face 3 is shaped to cause the heel to show a side face in exact alinement with the side face of the shoe heel when it has been attached thereto, 1n consequence of the natural action or change of position of the rubber heel, re-

sulting from the nailing operation, as

an upper beveled'face, a lower beveled face,-

and a side face that flares outward, the beveled portion'of the heel gradually degrea'sing in thickness toward the said side ace.

2. A rubber heel having an inside air chamber, a nail hole rim surrounding said air chamber, and a substantial upturned portion encircling the nail hole rim, said upturned portion having faces shaped to for the purposes de- 3. A rubber heel having a chamfered inner portion forming an unobstructed air cushion, aflat nail hole rim extending around said portion, a substantial upturned rim extending around the heel beyond the hole rim, the lower face of the up- "i'"ih[ed rim being beveled to a greater degree than the upper face, said lower face 110,,

eliminates the possibility of imperfect conbeing shaped to preseht a fiat wearing surfaceas the heel strikes the ground in ofdi- ,bottoin s lirfaces, the body between: said cen- .t-ral portion'and the =outer ed e s'bing inclined upwardly and outward y, the -lnclimation'of the bott0m"surfac e.;bei'ng greater Y than that of the upper surface.
